Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of a rolling roller gear sleeve of a slag processing device, in particular to a split gear sleeve of a slag rolling roller. Background Art
[0002] In metallurgical steelmaking enterprises, converter steelmaking slag (referred to as "steel slag") accounts for about 10% to 15% of crude steel output. The amount is very large. If it is not properly handled, it will easily cause long-term land occupation, environmental pollution and waste of resources. Therefore, the deep recycling of steel slag renewable resources is a kind of steel slag reprocessing that can turn waste into "treasure". It can crush, magnetically separate, separate, grind, and select the steel slag produced in the converter steelmaking process. Through the mechanical energy multiple reductions, the solid surface energy can be separated into a valuable metal circulation system. The separated steel particles can be directly returned to the steel mill for steelmaking. The fine steel slag powder after grinding can be selected into iron concentrate and returned to the steel mill for sintering. The mud washed with water can also be used as agricultural fertilizer. The remaining steel slag powder can be directly supplied to commercial concrete mixing stations for concrete production and mixed with slag powder and fly ash to form a composite powder, replacing 20% to 50% of ordinary Portland cement, and preparing C20 to C60 concrete of different strength grades with excellent performance, so that the comprehensive utilization rate of steel slag reaches nearly 100%, and "zero emission" is completely realized.
[0003] In order to overcome the shortcomings of the existing technical solutions, the structure of the gear sleeve of the slag treatment roller is mostly integrally cast. When the gear sleeve is working, the upper one-third or more of it is directly rolled with the slag, which is the fastest wear part, and the lower two-thirds of the gear sleeve is less worn. When the upper end of the gear sleeve is worn by 70%, it will be scrapped and replaced with a new gear sleeve. Through observation, the wear of the lower two-thirds is often not large, which often causes the waste of the gear sleeve. Utility Model Content
[0004] The utility model aims to provide a split gear sleeve of a slag rolling roller to solve the problems existing in the above-mentioned background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel slag rolling roller split gear sleeve, characterized in that: the steel slag rolling roller split gear sleeve is divided into a rolling roller upper tooth 3 and a rolling roller lower tooth 9, a dovetail 1 is provided below the rolling roller upper tooth 3, a dovetail groove 10 is provided at the top of the rolling roller lower tooth 9, and the dovetail 1 and the dovetail groove 10 fit each other; pin holes are symmetrically provided on both sides of the rolling roller upper tooth 3 and the rolling roller lower tooth 9, and are positioned by a tapered pin 4.
[0006] Preferably, an anti-retraction groove 5 is provided in the middle of the tapered pin 4.
[0007] Preferably, the upper teeth 3 of the rolling roller and the lower teeth 9 of the rolling roller are both provided with an inner cavity 2, and both are provided with a saddle threaded hole 7 inside, and are connected by an anti-retraction screw 6.
[0008] Preferably, the top end of the anti-retraction screw 6 is in the anti-retraction groove 5 .
[0009] Preferably, bolt holes 8 connected to the rolling roller are provided below the lower teeth 9 of the rolling roller, with four bolt holes 8 evenly distributed around the four sides.
[0010] Compared with the prior art, the beneficial effects of the utility model are: first, the purpose of split replacement can be achieved according to the wear conditions, the dovetail groove matching structure is relatively simple, and all the gear sleeves can be interchanged, saving the cost of purchasing spare parts; second, a stepped conical locating pin is used for locking to ensure the overall safety and firmness of the split gear sleeve during use; third, through the use of the split gear sleeve, the gear sleeve does not need to be replaced as a whole when it is worn out, and only one-third of the worn part needs to be replaced, and the spare parts cost is reduced by more than 55%. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 It is a structural schematic diagram of the utility model.
[0012] In the figure: 1. dovetail; 2. inner cavity; 3. upper teeth of rolling roller; 4. taper pin; 5. anti-backward groove; 6. anti-backward screw; 7. saddle threaded hole; 8. bolt hole; 9. lower teeth of rolling roller; 10. dovetail groove. DETAILED DESCRIPTION
[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0014] See also Figure 1 The utility model provides a technical solution: a slag rolling roller split gear sleeve, which is divided into a rolling roller upper tooth 3 and a rolling roller lower tooth 9. Pin holes are symmetrically arranged on both sides of the rolling roller upper tooth 3 and the rolling roller lower tooth 9, and are positioned by a tapered pin 4.
